` Specification of Letters Patent. Y

Application filled August 1, 1914. Serial No. 854,461.

To all whom t may concern.'

Be it known that I, WILLIAM R. PEN- SCHUCK, a citizen of the UnitedStates, re# siding at St. Paul, in the county of Ramsey and State ofMinnesota, have invented certain new and useful improvements in Engines,of which the following is a specilication.

The invention comprises a power plant consisting ofa. water supply,pumps for forcing the water into coils and a supply of compressed airfor forcing water from the coils into a steam 4 generator where it issprayed onto a hot plate thereby forming steam. The steam operates anengine of common type. The exhaust steam from the engine is led intotanks from which it is drawn by pumps operated from the engine andforced into a chamber to be raised to a higher' temperature.

A pump operated from the engine forces air through a chamber above thegenerato-r where it is heated and through another chamber where it isfurther heated by a lamp, after which it passes through a coil in theexhaust heating chamber and into said chamber through an escape valve toheat the exhaust steam. The exhaust from this chamber is used to run theair compressor to furnish thecompressed air.

To this end the invention consists in the construction, combination, andarrangement of parts hereinafter described` and claimed.

In the accompanying drawings. forming part of this specication, Figure 1is a side View of the apparatus; Fig.V 2 is a partial section through2-2 of Fig. 3; Fig. v3 is a top view; Fig. 4C shows valve operatingmechanism; Fig. 5 is a section through valve on line 5 5 of Fig. 1; Fig.6 is a section through valve in opened position; Fig. 7 is a sectionthrough valve in closed position; Fig. 8 is a section through exhausttank on line 8-8 of Fig. 1; Fig. 9 is an enlarged section throughgenerator and hot air tank on line 2-2 of Fig. 3; Fig. 10 is a sectionthrough generator and hot air tank on line 10-10 of Fig. 3, and Figs. 11and 12 are plan and side views, respectively, of a portion of the valvereversing mechanism.

The generator A employs a suitable heater 8 for converting into steamthe Water intermittently and alternately supplied by pipes B and C tothe superposed plate 52 of the casing or boiler 5l (Figs. 10 and 11).These pipes receive the Water from a Water tank 5 to which they areconnected, and as a motor for forcing the liquid through the pipes Iemploy compressed air from a'storage tank 6, the air supply beingreplenished through the instrumentality of an air compresser 33. A pipe7 conducts the air from Y the tank 6 to valves D and E, each of whichcomprises a fixed casing 53 and a rotatable core 54 provided with aplurality of ports, as depicted in Fig. 5. These valves operatealternately and perform like functions.

The ports 8u and 9L connect the pipe 7 i and the other port, 5a,admitting the steam through pipe 12a to the bottom of the cylinder` fordriving the piston 13 on both strokes. The exhaust port at the oppositeend of the cylinder isopened in the respective tank 14 (15) throughpipes 69 and 70 and valve ports 6aL and 7a, from which tanks the exhauststeam is alternately drawn through pipe 73 and port 10a, by pumps 24 and25, and forced through port 11a into the exhaust reheating tank 26.Subsequent to being reheated, the exhaust steam is conveyed by pipe 34for operating the engine` 32 of .the air compressor 33. From engine 32,the exhaust passes through pipe 35 to the water tank 5.

lVater is drawn from tank 5 through pipes 18, 19 and 20 and valve port2a by the respective one of pumps 16 and 17, and is forced through port1UL into coils B and to be further impelled by the compressed air. Theair within the coils is released by port 3EL to clear the coils for thenext admission or supply of water from the water tank. A passage 23relieves tank 5 from excessive pressure, which the exhaust steam mightotherwise afford. Pump 27 forces air through a heating chamber 28 forpreliminary heating and from there the heated air is conducted tochamber 29 where the temperature is further raised by lamp 30. Theheated air is then conducted into coils 31, varranged in tank 26, andescapes into the latter for heating the exhaust steam which latter issubsequently utilized for operating the engine 32, as previously setforth. The pistons the link 41, as at 58. Thus, it is obvious that Yrotation of the cam 33 Will depress the lever and, through the link andplate connections, eilect oscillatory movements of the disks 42 and 43and consequently, the valve cores.

As a means for holding the valves, as positioned by the cam 38, for apredetermined interval, fix on link 41 an arm 4G which, When elevated,Will o-verlie a stop 47. This stop is pivoted at 49 to a slide memberoperable by a crank 59, on shaft 21, to which it is connected by link50. A fixed cam 43 is arranged in the path of the stop 47 to remove thelatter from under the arm 46 and thereby permit of the valves returningto normal position for a subsequent operation by cam 38. As the stop 47is advanced toward the cam 48, it is obvious that the nose of the formerwill ride to an angular position as shown in Fig. 11. When the slidemember is retracted, a spring (not shown) will return the stop 47 tonormal position Where it will arrest the arm 46 when it is againelevated.

claim as my invention:

A povver plant of the class described consisting of a source of Watersupply, a generator, means for generating steam therein, an engineoperatively connected with the generator, means operable by the exhauststeam from the engine to compress air for forcing Water from said sourceof supply to the generator, tanks operatively connected with the exhaustport of the engine to re- Copies of this patent may be obtained forceive the exhaust steamk therefrom, means for forcing the exhaust steamfrom said tanks to a second chamber, an air tank heated by thegenerator, and means for conducting the heated air to the second chamberfor raising the temperature of the exhaust steam to operate said secondmeans.

2. A power plant consisting of an engine, a generator, a source of Watersupply for the generator, coils, means for forcing Water from the supplyto said coils, and an air compressor operable by the exhaust steam fromthe engine for supplying air to force the water from said coils into thesteam generator.
